testv24TagWithNonSyncSafeFrame()
This tests that we work out that the frame is not unsynced and read the frame size as a normal integer
using an integral algorithm

void

testv24TagWithNonSyncSafeFrame2()
This tests that we work out that the frame is not unsynced because its highest order bit size is set
and read the frame size as a normal integer using an integral algorithm

void

testv24TagWithNonSyncSafeFrame3()
This tests that we work out that the frame is not unsynced because frame only matches to next frame identifier
when not unsynced ( it is the USLT frame that is bering tested in this case, we only get to APIC if read
USLT frame ok)

void

testv24TagWithSyncSafeFrame()
This tests that we work out that the frame is unsynced and read the frame size correctly and convert to intger
this is what most (non-itunes applications do)

testv24TagWithNonSyncSafeFrame3

This tests that we work out that the frame is not unsynced because frame only matches to next frame identifier
when not unsynced ( it is the USLT frame that is bering tested in this case, we only get to APIC if read
USLT frame ok)
